FALL-ROPE CARRIER.

To all whom it may concern:

Be it known that we, JAMES GRANT DELANEY and AsHnR LAMBERT, bothcitizens of the United States, and residents oi Newark, in the county ofEssex and State of New Jersey, have invented a new and improvedFall-Rope Carrier, ol which the following is a full, clear, and exactdescription.

Applications tiled March 20, 1906, Serial No. 306970, issued August 28,i906, as Patent No. 829911, and application liled March 22, 1906, SerialNo. 307311, issued January 1, 1907, as Patent N o. 840443, are divisionsoi this application.

This invention relates to conveyers or cable ways for hoisting andconveying.

The object oi this invention is to provide a rope carrier which issimpler andless liable to derangement than any heretofore known or used.

1n conveyers oi this character it is desirable and necessary to supportsome or all of the liexible ropes employed from the main cable ortrackway so as to prevent sagging and interruption to the successfulmovement of the carrier, and so as to permit the raising and lowering oithe load or bucket from the load carriage at any point between theterminal stations. Each carrier is automatically movable at apredetermined and characteristic relative rate so as to maintain theproper space or distance between successive carriers. To attain thisobject each carrier is provided with a singlepropelling element, like agrooved wheel, or pulley; this wheel or element preferably engages theunder side oi the main track or cable and the upper' side oi the endlesshaul rope, the track, the wheel and the haul rope, are in one and thesame vertical plane and the resultant thrust of the haul rope forces thesingle wheel into engagement with the main track. This steadies thecarrier and prevents wabbling. With a grooved wheel of given diameterthe rate of advance movement is onehal the speed of the haul rope tosecure an increased speed oi movement the single wheel is provided withtwo peripheral contacts at diii'erent radial points. The haul rope ofsmaller diameter than the main track or cable engages the wheel at theshorter radial distance and the main cable engages the wlieel at thegreater radial distance. To provide these two peripheral contacts adeeper groove bisects the 'circumferential groove and in this deepergroove, the haul rope, of less diameter, engages the peripheral contactat the shorter radial distance.

This improvement also provides means to insure an effective yieldingengagement of the propelling wheel of the carrier between the haul ropeand the main cable, thus increasing the certainty of action and avoidingdestructive strain on the cable and sheaves.

Reference is to be had to the accompanying drawings orming a part ofthis speciiication in which simi- Specification of Letters Patent.

Application filed March 18, 1904. Serial No. 198,768.

lar characters of reference indicate corresponding parts in all thefigures.

Figure 1 is a side view of the propelling wheel and Fig. 2 is an endview thereof.

There is a main track vor cable 12, the haul rope or traverse rope isshown at 14. The iall rope 16 supplies means ior raising and loweringthe load.

The rope carrier is constructed with a frame 19, which may be oi anysuitable material-preferably consisting of iron cheek plates betweenwhich pass the cable 12, and the lower-run of the haul rope 14, thecheek plates of the frame 19 are secured by angle pieces 29 held inposition by suitable bolts. 1n the lower part oi the rope carrier is asheave or guide 20 ior the iall rope 16, and mounted in the upper partare two carrier wheels 21, 21, that run on the main cable 12 to supportthe rope carrier. The haul rope 14 runs over two sheaves 22, 22, mountedin the irame and suitably spaced with respect to each other.

The broad wheel'base due to the location of the sheaves 21, 21, invertical planes separated a distance about equal to a diameter of thedriving element 23, causes the barrier to maintain a vertical position;this is rendered still more stable by the similar location of thesheaves 22, 22. The position oi the rotary driving element 23 withrespect to the two pairs of sheaves21 and 22 is such that the trackcable 12 is pinched between the sheaves 21 and the driving element. Thisall contributes to the stability oi vertical position.

The form and disposition of the parts 12, 14, 20, 21, 22 and 23, are soregulated that both cables bear tightly against roller 23, the haul ropebeing sprung or bowed slightly at the opposite sides of the tractionroller. This causes the actuating rope in this instance the haul rope),to press the traction roller upward against the main cable and thusmaintain a firmyet elastic engagement between the parts 12 and 23, and14 and 23. In effect the roller or wheel 23 is gripped between the twocables.

With this apparatus, as the haul rope moves at a certain rate of speed,it imparts a rotary movement to the traction roller or driving member23, causing the roller to run along the stationary main cable l2 whilethe rope carrier is advanced at a lower speed than that of the haul rope14.

By varying the relative distances of the ropes 12 and 14 from the centeroi the traction roller 23, that is, by providing peripheral Contactpoints or faces at respectively different radial points, the speed atwhich the rope carrier is propelled with respect to the movement of thehaul rope 14 may be varied at pleasure. The drawings show an arrangementby which the rope carrier is made to run at three-quarters the speed ofthe haul rope. This is done by providing a single traction Wheel orroller 23, having two peripheral Contact points or aces 26 and 27, atdifferent radial distances; the peripheral contact or face 26 being onthe shorter radius and the peripheral contact or face 27 beingon thegreater radius. The haul rope 14 engages the shorter radial periphery 26while'the main cable 12 engages the longer radial periphery 27. Holes oropenings 28 for the adjustment of the sheaves 22 are shown in rows one'above another.

In the construction shown the shorter radial periph ery 26 is betweentwo annular flanges extending beyond the periphery 2G to form thegreater radial periphery 27. The haul rope 14 being smaller than theinain cable runs between these flange-like portions and bears on theperiphery 26 while the main cable 12 runs upon the outer edges oi saidflanges'.

In connection with the invention described it is pointed out that theemployment of a single propelling wheel 23 provides or maintaining theelements 12, 14, and 23, in the same vertical plane and accuratelybalancing the rope carrier thereon, thus avoiding the side lash orWabbling of the carriage, since the pressure between the parts is in thesarne plane and central of the carrier.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In a conveyer, a rope carrier having a frame, a traction rollercarried thereby and comprising a small face and flange-like portions ateach side thereof, projecting beyond the same and spaced from each otherto forni a large face, said faces being adapted respectively to engagethe haul rope and main cable.

2. A rope carrier for conveyer systems including a drivingroller havingtwo faces adapted respectively to be e11- gaged by the conveyer trackwayor main cable and the eonveyer haul rope, said faces of the rollerhavingl their een tral or middle planes coincident, for the purposespeciticd.

3. A rope carrier for conveyor systems havinga drivingroller with twofaces of different diameters adapted respectively to be engaged by theconveyor traelnvay or main cable and a haul rope, said faces of theroller having; their central or middle planes coincident, for thepurpose, speciiied.

4. In a conveyor system a track rope and a haul rope combined with arope carrier includii alitable trame with a single traction rollerhavingl sel the track rope and the haul rope, said roller en under sideo1' said track rope, a pair ol' anti-l vices running on said track ropeand means for holdin:l the haul rope in driving engagement with theunder side of said traction roller.

5. In a conveyer a rope carrier consisting ot' a, single tractionroller, a groove or face on said roller for the trat-li rope, a grooveor face on said roller for the hanl rope, a suitable frame supporting.:lsaid roller, and a pair ot' antifriction devices traveling` on the trackand means for hohlinglthe haul rope in propelling engagement with theunder side of said traction roller.

G. ln a convcycr system two ropes of respectively dit ferent diametercombined with a rope carrier consisting' ot' a frame, a single tractionroller supported in said trame. two grooves on said roller, having'their central planes coincident, correspondingl in diameter respectivelyto the diameter of the two ropes aforesaid, means for pressingl saidroller against the under side of one rope and means for pressing saidroller against the upper .side ot" the other rope.
